This file contains multiple Sacred 2 chests. Each folder contains a chest with complete sets of armor at the level designated by the folder name. The letter(s) following the number stand for:

B = Bronze

S = Silver

G = Gold

P = Platinum

N = Niobium

Therefore, the folder "15 BSG" contains three sets of level 15 armor, one dropped in Bronze, one in Silver and one in Gold. The armor otherwise is identical and offers the same bonuses available for that level, however, the higher level armor may have slightly higher values.

After you've backed up your chest.sacred2chest file from the above folder, copy the chest.sacred2chest file to your save game directory and restart your game. You can then find the armor in your shared belongings chest. Grab the armor pieces you want and then save your game and exit. You can then restore your normal chest.sacred2chest file to the Sacred 2 folder and restart and continue your game.
